3. Characteristics
Remark:
Reference level for the relative attenuation arel and the band width BW of the TFS 125 is the minimum of the pass band
attenuation amin. The minimum of the pass band attenuation amin is defined as the insertion loss ae. The reference frequency
fc is the arithmetic mean value of the upper and lower frequencies at the 2 dB filter attenuation level relative to the insertion
loss ae. The temperature coefficient of frequency TCf is valid both for the reference frequency fc and the frequency response of
the filter in the operating temperature range. The frequency shift of the filter in the operating temperature range is not included
in the production tolerance scheme.
